ok to run plug wires through a pipe

Angie · Mar 29, 2017

No idea if this is the proper spot for this question or not.

What would be the troubles with running 302 spark plug wires through a single tube on each side of the motor? have this neat set of wire loom tubes, but trying to find information about cross fire with 8MM taylor wires and if I am opening myself up for a world of troubles if I ran the wires in them.

can set them up mock and take a pic if need be.

thanks

Never seen that done before and I suspect it would be problematic if the shielding on the wires isn't good. Even with good shielding I've seen wires arcing out on other metal parts with a bit of moisture introduced to the mix.

And if the tube itself is metal...not sure if that would make things any better.

I've always ran them as far as possible with wire spacers as frequent as possible...but that may be a product of my buying cheap wires and the fact that there is plenty of moisture in the air where I live.

Do you have the product name by any chance? I'd be interested in reading more on it if it was mass produced...might be something there that I can learn from.

You could always try it and see if it works first. Depending on your pipe size you could also individually wrap each wire in an additional shielding material if you have problems.

Hi Mark, they are/were made in Canada from a company called vincore.ca dead web site. no idea if they are out of business or changed the name to something else. you can type vincore.ca into google and hit images to see other pics of them.

cheers

One of my tractors has them going thru a metal pipe from the factory. Many John Deere models did.

Mine only has points ignition (same as many pre HEI GM cars) and 7mm plug wires but I haven't heard of any problems. Might watch for vibration and rubbing thru the insulation (granted John Deere two cylinders run so smooth you can watch the bounce in the front tires as the engine hits)

I was changing oil this spring and noticed over the winter a mouse had chewed the boot off of one plug, it still doesn't arc to the shield. :dntknw:

I have a 70 2800 CS BMW that runs all 6 wires through a pipe like system. They come out near each plug. It was designed that way by BMW.

That is interesting, v6 or IL6? you ever had a problem with any ignition arcing?

thanks

Glad to hear this also

might be ok to run them... will be sticking grommets in the pipe holes for wire protection if I use them... thanks for the info. just mainly worried about cross jumping of the spark signal coming from a MSD AL6 and msd dizzy... can't see this being any concern... but never know.

thanks

true... don't know if there is enough room though. cheers

Thank you...I checked their website and it seems to have recently expired so it may be back up if they renew in time.

As I said, I've never seen this setup used but if it's good enough for a BMW and a tractor then I suppose it has some merits.

Personally though, I'd like to see the tube have an opening in the even that one of the wires should need replacing...I can see having to pull the whole thing off if that happened but these things usually only happen to me...lol...and likely the result of my own actions like getting a torch or other tool too close.

Heh heh My 528e I 6 had the wires in a snap together plastic thingy that was screwed down on the valve cover. A wire set was 275$ but were good for 20 yrs. Typical V8 wire mgt is those sheet metal brackets with a plastic piece to hold the wires in.

Really old ACVWs had a steel tube to hold long runs of high voltage ignition wire. They also had 6 volt electrical systems, manual chokes, and a reserve tap instead of a gas gauge.

Today the last metal guide holding wires I saw was from the street rod guys running v-8s. I would assume it is to keep the wires of the headers as they were aluminum and kind of blingy.

One big advantage of spiral wound plug wires is that they don't induce voltage into each other. You should be fine!

Actually it is easier than you think. the way these are designed, you place the spark plug end to the longest run then work back wards to the shortest. these are for the build your own plug wires. then after the plug ends are on the spark plugs, run the wires to the distributor and cut then crimp the ends to length for the 2 sides. if you get a bad wire or some thing, i would say you can pull the bad one out and re run a new one.

from your responses I will try them out and see how they work, I can't see any major problems . only thing i am a bit leery of is cutting down the wires and crimping them up to find out that they cross fire and send signals to the wrong pistons. chance i will take and at least I will know what the cause of the problem is,

cheers all
